P0176 Fuel Composition Sensor Circuit Fault

Fuel Composition Sensors are used to determine the amount of ethanol alcohol in the gasoline. Normally, a gasoline engine should not have more than 10% ethanol alcohol in the fuel for proper operation. Try getting fuel from a different place to see if that changes anything.

Let me know if it helps.
